Section 1. – Introduction
Thank you for purchasing a Chemflo feeder.
The Chemflo dosing unit is designed for maximum reliability to give you many years of service.
The Chemflo is easy to operate. This manual provides all the details required for correct
installation and operation of the unit. If at any stage you require assistance, please contact your
local dealer.
Please note that the Chemflo must be serviced or repaired by authorised personnel only. Opening
the unit by unauthorised persons may cause an electrical shock, resulting in serious injury or
death. If the power lead becomes damaged, the unit must be returned to your dealer or repaired by
an authorised person only.
1.1 Chemflo Diagram
1. Dosing Pump.................... This can be used for either Chlorine or Acid.
2. LED Display ...................... The display provides a visual indication of the dosing rate.
3. Dose Rate Control............ Set the control to add more or less chemical, turn dosing
OFF or allow the pump to operate continuously (eg. for
pool start-up or super-chlorinating).
4. Piggy-back power Plug ... Plug this into a 240V AC power outlet which is controlled
by a timer. The main pool pump then plugs into the piggy-
back plug. This ensures that the Chemflo only adds
chemical when the main pool pump is on.

Section 2. – Installation
The Chemflo is supplied with an installation guide. Installers should also refer to this guide.
2.1 Plan the installation
Ensure that…
1. The Chemflo feeder is installed in a sheltered location.
2. The Chemflo controller is close enough to the expected location of the Injection Tee for the
pump output tubing to reach without straining.
3. The maximum suction height from the bottom of the chemical drums to the dosing pump is 2
metres.
4. The mains power leads from the Chemflo and the Pool Pump reach a mains power outlet. If
the controller is mounted in a wet area, a weatherproof power outlet must be used. It is
recommended that you use an earth leakage circuit breaker with this power outlet. Please
consult a qualified electrician if you are not sure if this is fitted.
5. Install the Injection Tee
Install the Injection Tee as per the diagrams below. Use a suitable PVC joining compound. The
Tee is installed in the return line to the pool, as the pressure is lower.
